The equation for the least-squares regression line in the previous Example is $$\begin{gathered} y = 7.04 - 0.05x \end{gathered}$$

1. What values for the input variable make sense for the model?
   From to
   What is the largest value predicted by the model for the output variable
   What is the smallest value predicted by the model for the output variable
2. State the slope of the regression line, including units.
   A) biths per woman
   B) births per woman per percentage point
   C) literacy per percentage point
   D) women per birth
   Explain what the slope means in the context of the data.
   The birth rate decreases by :
   A) 0.05 births per woman for each percentage point increase in the female literacy rate.
   B) 0.05 births per year among literate women.
   C) 0.05 births per country for each percentage point increase in the female literacy rate.
   D) $-0.05$ births per women.
